Understanding the Human Senses

This video from Mumu Math and Science explores the five key senses: smell, vision, touch, balance, and hearing. It explains how each sense works, detailing the biological processes involved. The sense of smell is linked to memory, vision involves light processing in the eyes, touch is mediated by skin receptors, balance is controlled by the inner ear, and hearing involves sound wave processing in the ear. Each section provides a comprehensive overview of how these senses help us interact with the world.
